Nursery chair



Feb. 22, 1966 H. REHSTEINER NURSERY CHAIR Filed June 28, 1963 United States Patent 3,235,884 NURSERY CHAIR Hlne Rehsteiner, 13 Quai Capo dIstria, Geneva, Switzerland Filed June 28, 1963, Ser. No. 291,318 2 Claims. (Cl. 4-134) My invention has for its object a folding nursing chair incorporating a chamber pot, the novelty of which consists in that it includes in combination a folding support and an interchangeable container adapted to be fitted over said support and made of a simple sheet of plastic material.

More specifically, my invention has for its object a folding chamber pot comprising a seat to the underside of which are pivotally secured at least two feet adapted to be folded and to which is pivotally secured a flap forming a movable seat including, in combination with the former, stationary seat, means which allow clamping over the opening of the seat, the periphery of a sheet adapted to serve as a removable receiver or container.

In accordance with one embodiment of the means securing said sheet to the foldable support constituted by the stationary seat and its feet, said stationary seat carries a number of studs on its upper surface whereas the movable seat is provided in its lower surface with blind holes in which said studs may be fitted with the interposition of the sheet serving as a container so as to hold the latter in position.

The accompanying diagrammatic drawings illustrate by way of example and in a non-limiting sense a preferred embodiment of my invention.

In said drawings:

FIG. 1 is a perspective view in dot-and-dash lines of the sheet serving as a container, in its position of use.

FIG. 2 is a longitudinal vertical sectional view of the chamber pot.

FIGS. 3 and 4 are views of the chamber pot in its collapsed condition respectively as viewed from above and sideways.

The folding support forming part of the chamber pot includes chiefly two seats shown respectively at 2 and at 3 and pivotally connected together through the hinges 4 which allow folding back the upper movable seat 3 over the lower seat 2. To the underside of the lower seat 2 which is to be considered as a stationary seat, are pivotally connected through hinges 5 the feet 6 and 7 located respectively to the front and to the rear of the pot. The front foot 6 is given a generally rectangular or trapezoidal shape, while the rear foot 7 is given the shape of an inverted U adapted to match the outline of the foot 6 when the feet are both in their collapsed condition.

The stationary seat 2 carries studs or projections 8 registering with blind holes 9 formed in the lower surface of the movable seat 3. When the two seats are in contact, the upper seat 3 being folded over the lower seat 2, the studs 8 enter the holes 9. The support thus executed is practically flat in its folded condition as illustrated in FIGS. 3 and 4. The two seats 2 and 3 are in fact superposed and the two feet 6 and 7 are folded back over the lower surface of the lower stationary seat 2, the front foot 6 extending inside the outline of the rear foot 7 as illustrated in FIG. 3. The folding support is advantageously associated with a small-sized back 10 including an arm 12 of which the lower end is adapted to engage removably "ice an opening 13 formed in the rear portion of the movable seat 3.

When using the chamber pot, the folding support described is associated with a sheet of plastic material 14 the periphery of which is clamped as illustrated in FIGS. 1 and 2 between the two seats, the studs 8 on the seat 2 entering the holes 9 of the seat 3 with the interposition of the sheet 14. The latter which is thus suspended through its periphery to the seats 2 and 3 forms the container which may be cast away after use.

When not in use, my folding chamber pot may advantageously be carried inside a small bag which may carry furthermore a bundle of sheets of plastic material adapted to form as many containers, each adapted to be used only once.

What I claim is:

1. In a nursery chair, the combination of a main centrally apertured seat, collapsible feet pivotally secured to the underside of said main seat, an upper seat pivotally secured to the rear section of the main seat and provided with an aperture matching the aperture in the main seat upon pivotal shifting of the upper seat into position over the main seat, one of the seats being provided with a series of blind holes, studs carried by the seat and entering the blind holes When the upper seat has been set in position on the main seat, a container forming a chamber pot made of a sheet of plastic material and including an upper peripheral flange adapted to be clamped over the different studs inside the cooperating blind holes to be thereby held between the seats in their superimposed position.

2. In a nursery chair, the combination of a main centrally apertured seat, collapsible feet pivotally secured to the underside of said main seat, an upper seat pivotally secured to the rear section of the main seat and provided with an aperture matching the aperture in the main seat upon pivotal shifting of the upper seat into position over the main seat, one of the seats being provided with a series of blind holes, studs carried by the other seat and entering the blind holes when the upper seat has been set in position on the main seat the rear end of the upper seat being provided in its upper surface with a recess, a container forming a chamber pot made of a sheet of plastic material and including an upper peripheral flange adapted to be clamped over the different studs inside the cooperating blind holes to be thereby held between the two seats in their superimposed position and a small-sized back the lower end of which is removably fitted in the recess in the movable seat.
